In summary, there was a discrepancy on the magnitude of the earthquake near Masterton, New Zealand, with the USGS reporting a M4.8 and Geonet reporting a 5.2. The earthquake was felt by people in the vicinity and was followed by several smaller aftershocks. The USGS report was questioned due to their limited sensors in the region, while Geonet's report was deemed more reliable. The earthquake was strong enough to knock the froth off of someone's latte, but not felt by everyone in the area.

There is some discrepancy on the magnitude.

USGS reports - M4.8 - 12km WNW of Masterton, New Zealand

Location: Lat 40.932°S, Long 175.514°E

"In the minutes following the quake there were a series of smaller ones in the same area, measuring 2.9, 2.6, 3.2, and 3.3."

Did you get a signal Dave?

yeah, I will believe the GNS report for this one. They have a very good saturation of sensors over the region
where as the closest 2 for the USGS are Wellington, NZ and Raoul Is, (NZ) around 500km nth of the North Island, NZ

only just saw some of the surface waves

Quite rich in small aftershocks, here's the last 24 hour
This also helps to confirm the M5+ status :)

I was in the shower at the time, and my dad came in and asked if I felt the earthquake -- I didn't. It seems it occurred right below Masterton's water treatment plant.

A guy on the radio asked if it knocked the froth off of your Latte :-)
